Downward License Compatibility Using FlexNet Publisher
FlexNet Publisher license servers have downward compatibility with PTC applications using FLEXlm license servers. For example, a Creo View 2.0 license can run ProductView 9.1 software, because both releases of the software use the same PTC License Server.
* 
To run the current release of Creo View, you must install FlexNet Publisher version 10.8.x or later.
